Man that estimate is nuts !! I recently had my fuel pump go out and luckily had a spare factory pump I had bought for that reason. I replaced it in a hour thanks to It having a access port under the back seat . So for $100 bucks and a hours time it was done. I went back through my receipts from the PO and found where he had had it done years ago at a dealer who charged him $985 to replace the pump. As others have said I try to do all I can my self. With this great resource in Mud and there being you tube vids of about everything it can be done. Glad you posted the stealerships name and declined thier work.
